i was asked by an instructor if a guy i did not know could follow our five way to film it,even though it was an instructor i asked them about his capabilities to carry out the jump and was assured he was ok to do so.in the plane it was noticed he was not wearing a camera and was asked why not.we was told he was practicing as he had not got a camera yet,it was to late to query further he impacted me as i docked it turned out he did not have enough jumps to jump camera and had spent the last 50 or so jumps freeflying and was not current with flatflying
